Yi Chuan : Theory and Applications (Chinese Internal Martial Art)
by Shou-Yu Liang and Jwing-Ming Yang, Paperback (June 1990) YMAA
Pubns; ISBN: 0940871084
A great book from YMAA.
Includes a long history of Yueh Fei, basic exercises and several
introductory forms. Good translation of the Chinese text. However,
it is not for novices: You should know something about Hsing Yi
to really appreciate this book.
